Guillermo is editor of fortnightly newsletter Mobile Media and of the Content & Applications Intelligence Centre, a web-based service that aggregates information on mobile data services from all publications at Informa.

In his role Guillermo is responsible for much of the journalistic coverage provided by Informa of the mobile content and data applications industry globally - everything from breaking news and exposés to market analyses and profile pieces.

Guillermo has recently written exposés on the revenue deals struck between mobile operators and the big online-search brands and on the failure of GSM carriers in the US to monetise the expensive mobile location systems they’ve deployed under the E911 mandate. He was also the first to break the news of Orange and T-Mobile joining forces to trial MBMS mobile TV technology TDTV in the UK.

Guillermo is an experienced journalist who has worked in business and current affairs journalism in Europe and Latin America. He has edited an aviation business title, worked as a newspaper reporter and foreign correspondent in Central America and Mexico City, and first became involved with Informa as a stringer for Latincom in Mexico. For the past four years he has worked as part of Informa’s Content & Applications editorial team, first as editor of Mobile Location Analyst, Mobile Enterprise Analyst and Mobile Messaging Analyst, and now as editor of Mobile Media.
